MACHINE FOR SOWING FERTILIZERS.

SPECIFICATION forming part of Letters Patent No. 265,529, dated October3, 1882.

(Model.)

To all whom it may concern:

Be it known that I, EDWIN D. MEAD, a citizen of the United States, and aresident of Shortsville, in the county of Ontario and State of New York,have invented certain new and useful Improvements in Machines for SowingFertilizers, of which the followingis a specification.

My invention relates to an improvement in.

1o machines for sowing fertilizers, and more particula-rly to that classwhich employs a rotating disk in combination with a revolvingcleaner-Wheel, as shown in Letters Patent granted to me August 19, 1879,my invention herein containing certain improvements upon said patent,and consisting, first, in providing a bent shaft containing a stud orcrank upon each end thereof, one forming the axis for the revolvingfeed-wheel and the other stud fornizo ing the axis for thecleaning-wheel, which revolves eccentrically to the center of motion ofthe distributing or feed wheel.

My invent-ion further consists in adapting the arm of the bent axle,which lies withinthc z5 concavity of the cleaner-wheel, to act as ascraper to scrape oft' material sticking to the concave surface.

My invention further consists in a gate or cut-oli' valve which isplaced above the discharge-orifice and oscillates vertically over thedischarge-orifice and cleaner-wheel, so as to regulate lthe low of thefertilizing material through the oritice.

My invention further consists in providing an annular peripheralbearing` for the distributing-disk, in combination with an oil-cup onthe outside of the feed cup or hopper, and connected to the annularbearing by an oritice pierced through the side walls and leading 4o fromthe oil-cup to the annular bearing, so that the peripheral bearing ofthe feed-wheel can be readily supplied with oil from the outside of thehopper.

My invention further consists in providing on the peripheral edge of therotating disk or feed-wheel a projecting lug, which fits close to theside wall of the feed-chamber and acts as a scraper to prevent thesticking of the fertilizer material to the side walls and clogging themachine.

My invention consists, finally, in placing the discharge-oriiice insidethe feed-cup, so as to be protected from the wind, which would otherwiseblow the nely-powdered fertilizer material about.

Myimprovements will be more fully setforth in the following descriptionof the accompanying drawings.

In the accompanying drawings, Figure I is a plan view ot' the feed-cup,showing the ro- 6o tating diskor'eed-wheeland the cleaner-wheel. Fig. 2is a vertical section of the same on line a' x of Fig. l. Fig. 3 is aplan view of the feed-cup with the wheels removed, and showing thespider-arms underneath. Fig. etis a bottom plan of cleaner-wheel,showing the bent shaft or stud.

A represents the rotating disk or feed-Wheel B, the cleaner-Wheelworking upon it. O represents the bent shaft or stud; l), the side 7owall of feed-cup. @represents the side scraper, which is preferably madeby projecting outward and upward one'of the carrying-teeth ot' thefeed-wheel A. b represents the oil-cup c, the axle formed by the bentshaft or stud O upon which the Wheel A revolves. c' represents the pivotor axle by shaft O upon which the cleaner-wheel B revolves. tlrepresents the annular groove forming the peripheral bearing for wheelA;E, the discharge-orifice; 8o c, a vertical flange upon the under side ofthe periphery of the disk or feed-wheel A, which works in the annulargroove d. F represents a horizontal lange on the lower edge of the wallof the feedchamber, upon which the disk A rests, and in which theannular groove d is cast. Gr Gr represent the spider-arms. 'g representsgearing on the under side ot the periphery of disk A. g representsgearing upon the continuous shaft H, workinginto gear- 9o ing g andoperating disk A. L represents the gate or cutoff valve; l, the rodwhich operates the gate L; h, a holt or screw which secures the bentshaft or stud C to the spiderarms Gr.

My device has a lug, h', on the lower end of the bent shaft or stud C,which lits into a correspondingly-shaped opening, h", in the spiderarms,and holds it stationary, so as to prevent its turning with disk A. Theupper side of 10o the periphery 0l' the wheel A is provided with theannular peripheral bearing ot' wheel A, 45

a series of lugs or carrying-teeth, t' fl, perpendicular to the face ofthe wheel and meshing into the periphery of the cleaner-wheel B. Thefertilizer material is carried around upon the face of the plate A inthe direction of the arrow in the accompanying drawings, and all lumpsare broken and crushed between the cleaner-wheel B and the side wall ofthe feedehamber before it passes into the dischargeorifice E. By therotation ofthe wheel B the fertilizer is forced into the orifice E.

The gate L, when down, lits closely over part of the top surface of thecleaner-wheelB, and acts as a scraper to keep the fertilizer fromadhering to it.

The bent shaft C also lits closely to the inside of the periphery of thecleaner-wheel B, and acts as a scraper to prevent the material fromsticking to the inner or concave surface of the wheel B.

Having thus described my invention, what I claim as new is as l'ollows:

1. A bent shaft or stud, C, forming aneccentric axle, c', for thecleanenwheel B to revolve upon, and also forming an axle for thehorizontal rotating disk or feed-wheel A, substantially as herein setforth.

2. In combination with thefeed-wheel A and the concave cleaner-wheel B,the bent axle C, located within the concavity ot' wheel B, and acting asa scraper to prevent the sticking of the material to the wheel,substantially as herein set forth. l

3. The combination, with feed and cleaner wheels, ofthevertically-oscillating gate or cutolil L, with its rod l, located tooscillate over the cleaner-wheel and above the dischargeorifice E, andadapted, when down, to act as a scraper for the cleaner-wheel.

4. The combination,in a machine for sowing fertilizers, of thefeed-wheel, with the oil-cup l) on the sidewall, D, of the feed-chamber,connected by an orifice through said wall with whereby the parts arekept lubricated, sub stantially as herein described.

5. The horizontal revolving whcel A, having a series of lugs or startsfor carrying the fertilizer arranged around upon the periphery of thewheel, with one or more of said lugs A projecting outwardly and actingas a scraper to scrape the fertilizer from the side walls of thcfeed-cup, to prevent the clogging of the feed wheel or disk,substantially as shown and described.

6. In a fertilizer-distributer, a metallic feed cup or hopper, withcylindrical sides D, and provided with the vertical discharge-orifice E,located within said feed-cup and abutting` the peripheries of the wheelsA and B, substantially as herein set forth.

7. The horizontal revolving wheel A, for carrying' the fertilizer,revolving within a feedcup and provided with an upwardly-projecting lugabutting the inner periphery of the feedcup and acting as a scraper toclean the fcrtilizer from the side walls of the feed-cup and to preventthe sticking of the fertilizer' to thc walls thereof, substantially asshown and described.

S. A fertilizer-distributer composed essentially of a feed-cup havingcylindrical sides and a feed disk or wheel' revolving therein againstsuch sides, the said f'eed'cup being cast or otherwise formed with alaterally-extending recess in one of'its sides, which recess containsthe vertically-discharging orilice, having its edge abutting theperiphery ot' the feed-disk, substantiaily as shown and described.

In testimony whereof I have hereunto set myhand in the presence of twosubscribing witnesses.

EDWIN D. MEAD.
